摘　　要：为筛选出适宜南阳地区种植的烤烟品种,对9个不同基因型烤烟的物理性状、化学成分、中性致香物质含量和经济性状进行了分析。结果表明:参试基因型烤烟烟叶的填充值、叶片厚度、拉力以及抗张强度均在适宜的范围,CF202和优选1号的烟叶平衡含水率较小。离子云烟85的叶片厚度较大。同一地区不同基因型烤烟的绝大多数化学成分在适宜范围内;8302、CF202和CF205的氮碱比和糖碱比比较适宜,Y041、云烟202和NK4的钾氯比相对较大。不同基因型烤烟的致香物质总量表现为CF205>Y041>CF202>8302>Y017>优选1号>NK4>云烟202>离子云烟85。CF202、CF205、Y041和NK4的产量、产值较高,CF202、CF205和Y041上等烟比例和均价较高。综合分析认为,适合在南阳种植的烤烟品种为CF202、CF205和Y041。To identify the suitable tobacco variety in Nanyang region, the physical properties, chemical components,content of the neutral aroma and output value of flue-cured tobacco with 9 different genotypes were tested. The results showed that the filling value, thickness of leaves, dragging force, and tensile strength were relatively suitable. The equilibrium moisture content was lower in CF205 and Youxuan 1. The thickness of Liziyunyan 85 was the biggest. Different genotypic flue-cured tobacco leaves had different chemical components in the same place, but most chemical components were harmonious. The ratios of total nitrogen to nicotine and total sugar to nicotine were always in optimum range,the ratio of potassium to chlorine was kept at higher level in Y041,Yunyan 202 and NK4. Aroma content of different genotypic flue-cured tobacco showed CF205;Y041;CF202;8302;Y017;Youxuan 1〉NK4;Yunyan202;〉Liziyunyan85. The yield and output value ranked higher in CF202, CF205, Y041 and NK4. The high-quality ratio and average price were higher in CF202,CF205 and Y041. In summary,CF202,CF205,and Y041 exhibited better leave qualities and were suitable for planting in Nanyang.
